I think the current Russia-Ukraine war is the delayed end of Soviet Union collapse.

Boris Yeltsin in Aug 1991 called for "Russian Federation to reserve the right to review its borders with any adjacent republic" [0]. Yeltsin did that for a couple of weeks - until Leonid Kravchuk (Ukraine's last Chairman of the Supreme Soviet of the Ukrainian SSR and Republic of Ukraine's first president) said he will not support Yeltsin in dissolving USSR. By then the Baltics were already independent countries, but Yeltsin still needed Ukraine's Belarus' and Kazakhstan's support to get rid of Gorbachev.

So Yeltsin acquiesced the borders at that time, four months followed up with the Belovezha Accords and USSR dissolved without a fight a couple of weeks later.

I think what we see today is are some repressed conflicts being fought out in the open.
